A Hyper-V Host status in VMM 2022 shows ' Needs Attention' with error complaining about not reaching the Network controller IP.

Hello Team,

I've installed the Network Controller in a two-node Hyper-V cluster and things were working fine for 2 weeks. After one of the nodes crashed and restarted, it started complaining about the connection issue with the REST IP address.

2 node cluster with Windows Server 2022 Datacenter Edition
VMM 2022 version 10.22.1711.0

Below is the error

Error (21426)
